Picked up one of these at Stansted on Friday- appreciate it isn't widely available but it's a great price for a bluetooth laser mouse. It has a really nice solid feel to it, not too heavy or light, it even combines a modern and classic design (if thats what you look for in a mouse). It also has a mode for it to be used as a presentation pointer thing. It didn't come with a dongle but I imagine most would own a bluetooth dongle already. Plus it has a five year warranty. Cheapest elsewhere seems to be around £30 at the moment.
